Supwhereby ported above the trough 2 are the s rocket wheels 4fast on the shafts 5 journale in the supports 5a, it being understoodthat said sprocket wheels 4 are adapted to impart motlon to the s rocketchains 6 that engage therewith an(h are provided with the projectingmembers or iingers 7 for a purpose hereinafter described. The supportsor standards 5a are braced by the bars 8 whose outer ends are inclinedas at 9, in the left hand portion of Fig. 1, it being noted that the oposite ends of said bars 8 are each provide with a depression 10adjacent the inner extremities of the inclined arms l11, in the 4righthand portion of Fig. 1, it being further noted that said arms l1 arepivoted at 12 to any convenient fixed point, in the present instance, inthe end portions of the brace bar 8.

13 designates standards in which is journaled a shaft 14 to which issecured the hand wheel 15 whereby said shaft may be rotated whendesired, it being noted that the latter is provided with acounterbalance 16 and the projecting members 17, as best seenin Figs. 1,2 and 7 and for. a purpose hereinafter described. The standards 13, inthe resent instance, are adjacent the inclined ars or rails 18 that leadto the horizontal ways' 19 which are formed with the curved portions 20as bestseen in Figs. 1 and 7, and for a purpose hereinafter described.The curved portions 20 lead to the inclined surfaces 21, that are inalinement with the upper surfaces 22 in the members 23 of the arms orlevers 24 when the latter are in their normal positions as seen in Fig.1, The portions 25 of the arms 24 adjacent the portions 23fthereof areinthe form of hooks as best seen in Figs 1 4and 7. The arms 24 rejectfrom a s eeve 26 loosely fitted on a s aft 27 v'ournaled in the supportsor standards 28. j he sleeve 26 has secured thereon, ,the hand Wheel 29said sleeve 26 may be rotated when desired. The sleeve 26 has securedthereon, a clutch member 30 adapted to cc-act with the clutch member 31loosely itted on the collar 26, as best seen in Fig. 4, it being notedthat said clutch member 31 is provided with an arm 32 whose outerextremity is formed with a socket 33, see also Figs. 1, 8 and 9, inwhich is located the spherical ortion 34 of the rod 35 whereby a ball ansocket con nection exists between said arm 32 and the rod 35, it beingnoted that a` nut 36 is em- .ofabe ployed to retain the sphere or ball34 in roper position within the socket 33. The ower extremity of the rod35 is connected to the strap 37 of an eccentric 38 fast on a shaft 39 towhich motion may be imparted in any well known manner, as for instanceby an engine, dynamo, etc. Theshaft 39 has fitted thereon, a sleeve 40,see Figs. 1 and 7, that is adapted to be rotated by said shaft 39 whileat the same time said sleeve may be shifted on the shaft 39.and in thedirection of its length for a purpose hereinafter described. The sleeve40 is provided `with the clutch members 41 and 42, the

former of which is adapted to co-act with a clutch member 43 in a pulley44lloose on the shaft 39, while the clutch member 42 co-acts with avclutch member 45 in a pulley 46 loose on the'shaft 39.

47 designates a belt that passes partly around the pulle s 44 and 48,the latter b ein fast on the slliaft 49 that is journaled in pi owblocks 50, it being noted that said shaft 49 has fast thereon, a bevelpinion 51 that meshes with a bevel gear wheel 52 fast on a shaft 53,journaled in the standard 54; and having secured thereon, a worm 55 thatengages the Worm wheel56 fast on the shaft 5, whereby when motion isimparted to said worm wheel 56, the sprocket wheels 4 are caused to turnin unison therewith.

The ulley 46 has secured thereto, one end lt or'cord 57 whose oppositeend is scured to a pulley 58 fast on the shaft 59 journaled in standards60, A it being noted that said 'shaft 59 has fast thereon, the pulleys61 and to each of which latter is secured the end of a chain, cord,etc.62, the opposite .ends of which are secured at 63 to a pan 64 hingedatV 65, to a trough 66 to which latter water is supplied through thevpipe 67, as seen in Fig. 4. The trough 66 1s provided with a dischargeipe 68. The pan 64 isv provided with per orations69. to permit the water70 to escape from said pan when the latter is in its elevated position,as indicated in dottedN lines in the right hand portion of Fha' sleeve40 is provided with a grooved collar 71 that moves in unison therewithand is enga ed by the free end 72 of a lever 7 3 fulcrume to/someconvenientiixed point as at 74, said arm having pivoted thereto one endof a link 75 whose opposite end is pivoted at 7\6 to one end of a lever77 fulcrumed at 78 in a standard 79. The lever 77 is provided with alocking device 80 whereby the formermay'be retained in one or the`otherof the three posions it may occupy, fora purpose l hereinafterdescribed.

. 81 designates aV rod, one end of which is pivoted at 82 to the lever77 while its op osite end is pivoted at 83 to the lever 84 ulcrumed at85 to a standard 86, said lever 84l being provided with a locking`device 87 similar to the'locking device 80. The locking devices 80 and87 can be rendered inoperative when desired by means of the catches 96and with a head or enlarged portion 92 'adapted' to travel in the groove93 in the rails 18 and ways 19 whereby, said baskets 88 are properlyguided when acted upon by the sprocket chain 6. The operation of thedevice is as follows:-

A receptacle 88 isplaced in the device by loeating the handles 90 and 91u' on the proj ecti'ng members 17, it being un erstood that there aretwo of these latter, as seen in Fig. 8, one of whichsupp'orts the arm90, while the other supports the arm 91, see Fig. 1. The receptac e 88thus sup orted is supplied with the articles to be .ga vanized orotherwise coated. The o erator adjacent the hand wheel 15 turns t elatter in the direction indicated by the arrow a in Fig. 1, whereuponthe members 17 arebrought into the osition Aseen in Fig. 2, therebypermitting t e handles 90 and 91 to slide down the rails 18 and restupon the ways 19 thereby causing said receptacle 88 and its contents tosink into the molten coating `'material or composition 38, after whichthe operator returns the hand Wheel 15 and consequently the projectingmembers 17 to their normal positions as seen in Fig. 1. The operatorthen throws the le'- ver 84 from left to right, see Fig. 7, whereu onthe lever 77 is caused to move in unison with the lever 84 by reason ofthe connecting rod or link 81. It will thus be seen that a pull isexerted upon the link 75 thereby turn- 'mgthe arm or lever 73npon itspivot 74 thereby shifting collar 40 from right to left and causing theclutch member 41 to engage the clutch member 43 and thus impart motionto the pulley 44, it being assumed that the shaft 39 is rotating. Themotion of the pulley 44 transmits motion to the pulley 48 y reason ofthe belt 47, whereupon the shaft 49 and the bevel pinion 51 fast thereonare caused'td rotate in unison. The rotary motion. of the pinion 51imparts motion 'to the bevel gear wheel 52 and consequently to the shaft53, the worm 55, the. worm wheel`56, its shaft 5 ands rocket wheels 4fast thereon, said sprocket w eels 4 im arting motion to the s rocketchains 6 and t e fingers 7 there'- v on, t y ereby causin the latter totravel in the direction indicate by the arrow b in Fig. 1, it beingunderstood that said fin ers 7 are broughtr against the handles 90 an.91 of the Areceptacles 88, that lie in their pathl as illustrated inFig. 1.v

Itis applarent that each receptacle 88y is laced in t e device in themanner hereinbeore described and that the clutch members yioo 41 and 43are disengagedsoas to bring the sprocket chain 6 to a stop each time areceptacle 88 is placed in the device.

The receptacles 88 and their contents are carried through the coatingcomposition 3 and when the handles 9() and 91 reach the curved portionsthey are guided thereby to the inclined surfaces 21 and slide down thelatter and drop into the hook portions 25 of the arms 24 as seen in Fig.1, the sprocket chains being again brought to a stop by shifting theclutch member 41. The operator adjacent the hand wheel 29 now operatesthe handle 94, see Figs. l4 and 5, whereupon the clutch member 31 isbrought into engagement with the clutch member whereupon the rockingmotionpof the shaft 27 is transmitted to the arms 24 and receptacle 88suspended thereon, whereby the superiiuous coating composition is shakenoff the articles within said receptacle.

It is to be understood-that the shaft 39 and the eccentric 88 thereon,as also the eccentric rod 35, the arm 32 and the shaft 27 and sleeve 40are in constant motion, when the machine is in use and that the arms 24are rocked only when the clutch members 30 and 31 are interlocked ashereinbefore described.

When the removal of the superfluous coating material is accomplished,the operator adjacent the hand wheel 29 turns the latter in thedirection indicated by the arrow c in Fig. 1 'whereupon the arms 24 andthe receptacle 88 suspended thereon are moved from the positions seen insaid Fig. 1 into those seen in Fig. 7, it being noted that thereceptacle 88 is now in a position to discharge its contents into achute 95 that directs said contents to the pan 64 so that the coated orgalvanized articles may be cooled by the-water in the trough 66, afterwhich the pan 64 is tilted or brought from the position seen in fulllines in Fig. 1 to that seen in dotted lines in said 'figure so as todischarge the cooled articles into a suitable receptacle.

The tilting of the pan 64 is accomplished by throwing the lever 77 tothe left of its position seen in Fig. 7 whereupon the clutch member 42is caused to engage the clutch member 45 thus imparting motion to thepulley 46 and consequently to the cord 57, the pulley 58, the shaft 59and pulley 61 fast thereon, whereupon a pull is exerted on the cord 62causing the latter to turn the pan 64 on its hinges 65. When the clutchmembers 42 and 45 are disengaged, by the operation of the lever 77, thepan position by gravity. j

It will be noted on referring to Fig. 1, that when the hand wheel 29 isturned in the direction indicated by the arrow c, it causes thereceptacle 88 suspended from the arms 24 to travel in the directionindicated by the arrow d, whereupon it will be seen that the 64 returnsto its normal handles 90 and 91 pass under the arms 11 and cause thelatter to turn cn their pivot 12 into the position indicated in dottedlines. As soon as the handles 90 and 91 reach a point beyond theextremities of the arms 11, the latter drop into their normal positionsseen in full linesin Fig. 1, so that when said receptacle 88 is movedfrom the position seen in Fig. 7 and in the direction indicated by thearrow c, the handles 90 and 91 are caused to engage the upper surfacesof the arms 11 and be directed thereby to the depressions 10 in the bars8 whereupon said handles 9() and .91 are in the path of the fingers 7 soas to be carried by the latter to their original or initial positions onthe projecting members 17 -and thus retain the receptacle 88 in theproper position to be again supplied with articles to be galvanized orcoated as hereinbefore described.

While I have shown in the drawings a machine which I know in practiceoperates successfully, it will be evident that various changes may bemade therein and other instrumentalities may be used which will operatesatisfactorily, and I therefore do not desire to be limited in everyinstance to the exact form as herein shown and described, but desire tomake such changes `within the sco e` of the claims as may be necessary.
